20130279296 | TRACKING SYSTEM FOR A PIPELINE - A tracking system for use with a pipeline includes a scraper having signal generation capability for generating acoustic signals, a plurality of acoustic pressure sensors positioned at intervals along the path traveled by the scraper, and a plurality of local processors positioned at intervals along the path traveled by the scraper. Each of the local processors is in communication with a respective acoustic pressure sensor. A central processor is in communication with the local processors and determines the location of the scraper using time-stamped acoustic signals received by the pressure sensors and a speed of sound in a fluid within the pipeline. | 10-24-2013 |
20130276250 | Trackable pipeline scraper for active tracking and locating - A tracking system for use with a pipeline includes a scraper having signal generation capability for generating acoustic signals, a plurality of acoustic pressure sensors positioned at intervals along the path traveled by the scraper, and a plurality of local processors positioned at intervals along the path traveled by the scraper. Each of the local processors is m communication with a respective acoustic pressure sensor. A central processor is in communication with the local processors and determines the location of the scraper using time-stamped acoustic signals received by the pressure sensors and a speed of sound, in a fluid within the pipeline. | 10-24-2013 |

20110093220 | INTEGRATED ACOUSTIC LEAK DETECTION SYSTEM USING INTRUSIVE AND NON-INTRUSIVE SENSORS - A system for detecting and locating leaks includes a pipeline, strain sensors positioned on the external surface of the pipeline, acoustic pressure sensors positioned at intervals along the pipeline, local processors connected to the strain sensors and acoustic pressure sensors, and a central processor connected to the local processors. The strain sensors measure a strain on the external surface of the pipeline indicative of changes in the pressure of the fluid within the pipeline. The acoustic pressure sensors sense acoustic signals within the pipline. Sensed acoustic pressure signals and sensed strain measurements are compared to each other and to stored profiles to detect and locate leaks. | 04-21-2011 |
